To all whom it may concern: 1 of the usual construction comprising a bot- Be it known that I, Fain) GRUB, a citizen tom 8, a top 9, and a rear wall 10.

A fuel of which the following is a full, clear,'a1 d burner letis disposed between bottom 8 and exact description. an opening 15 in top 9 which is provided The invention relates to gaseous "fuel with anannulairecess 16 in which the cover .10 stoves and more particularly to those stoves plate is adapted to be positioned and held.

By means of this arrangement it will be readily seen that when the ou't'erand inner members are rotated relatively to each other and the slots 32'aiid 33 bro'ugl-it into register, that the slots on the flanges'will not bein register'with each other (as shown in Fig. 3), and all the' heat generated by the burner Willbe transmitted directly to the cover plate. tively to each' ot'her so that the slots 32 and 83 are not in regi'ster, it will readily be seen that'the slots 34 and '35 in the flanges will be in alignment so that the'heat and smoke will notbe' transmitted through the cover plate but will pass along-the top 9 of the stove and into thechimney.

The cover plate isprovided with means for manually moving the two members relatively to each other which comprises an arc;

.uate slot'38 extending through the 'outer' member '20 and a lug 39 rigidly secured to the inner me'iiiber-QIand extending through said slot.' Ridges etOj may be" integrally formed on-the outernien'iber 20 and radially disposedv'ith respect'to the bolt 22so that cooltingrec'eptacles may be held above the cover plate in spaced relation.
